Error Diagnosis and Troubleshooting
Alarm, Warning
If an impending defect is detected early enough, motor damage can be minimized. This leads
to:
• Lower repair costs
• Less downtime (increased productivity)
Alarm thresholds can be set for:
• Thermal utilization of the motor
• Overcurrent
• Asymmetry
• Underload
• Earth (ground) fault with core balance transformer
• Stator and bearing temperature with PT100
When the alarm threshold is reached, the LED flashes, the LCD indicates the type of alarm,
and the selected output relay picks up.
Procedure when Alarm/Warning Picks Up
EXAMPLE
Asymmetry
When an asymmetry condition occurs and the related threshold is reached, the following
responses occur:
• LED flashes
• LCD:
• The assigned output relay picks up
AS WARNING
